I am wondering if anyone knows if you can network Norstar MICS and a Siemens Hicom 300E. The 300E will be the main switch of course. I want to connect them using a point to point T1. I know that DID's will route to the norstar and work fine on incoming calls. I do not know if the norstar user can use the outgoing PRI's in the 300E. All outgoing calls would need to go through the 300E. It is QSIG.

Use PRI instead between the two switches...should not be a problem and gives you CLID, etc..
